paratus and is designed more particularly for the equip- I heated in said chamber, will also serve to prevent the ment of seli-propelled vehicles.

The primary object of the invention is to produce an apparatus for generating what is known as producer gas ironra body of coal in it novel manner which will insure the heating of the air to a high temperature before it is admitted to the generator, thus avoiding cooling oi the latter and facilitating the production of gas rich in hydrogen.

Another object of the invention is to produce agenerator of simple and durable construction composed of the least possible number of parts assembled in a manner to facilitate their disorganization for purposes of cleaning and repair, and their re-assemblage, Without the employment of skilled labor.

Another object is to so dispose the coal hopper with reference toan aunula-rair chamber in communication with the air inlet, that the cool air, while initially wall of the hopper from being raised to a high temperature and thus aid in preventing the ignition'oi the coal before the latter is fed to the combustion chamber.

A still further object is to devise a novel form of mounting for the grate, whereby the latter may be readily manipulated irom the exterior of the generator or entirely withdrawn from the generator, us circum-- stances may require.

To the mcomplishment oi the foregoing objects, and others subordinate thereto, the preferred embodiment of the invention resides in those features of construction and arrangement to be hereinafter described, illus I trated in the accompanying drawings, and succinctly defiiied inthe, appended claims.

In said drawingsFigure 1 is a sectional view of the generator. Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 3 is a similar view on the line 33 of Fig. 1. t p

Each part is indicated by the same reference numoral throughout the views.

- The generator comprises top and bottom members and 16 disposed in spaced relation and connected by hollow tie-rods 17 which constitute. tubes or conduits for the passage of moistened air. The upper member 15 of the generator is preferably in the form of a hollow casting defining a. fuel chamber 18 having a hopper bottom 19 surrounded by an annular airchamber 20 I its seat by spring 24 bearing at one end against the cap 23 and at its opposite end against the hand wheel 25 of a cap retaining device having the form or a screw 26 having its lower end screwed to a cross-bar 27 of the member 15. That portion ofthe screw 26 which passes through the cap is of plain cylindrical form, as shown, in order to permit the screw to move endwise for the unscrewing the screw 26, the cap 23 may be removed to facilitate the introduction of fuel or to give free vent cooling down when the motor is at a standstill. The cap is accurately fitted, however, .so as to absolutely exclude air when the motor is running.

The upper ends of the air tubes 17 open into the annular upper air chamber 20 and their lower ends open into a lower air chamber 28 defined within the lower member 16 of-the generator. The open lower side of the member 16 is closed by a cap 29 retained in place by hinged bolts 30 carried by the wall of the member 16 and received within notches 31 in the outer edge of the cap. When the cap 29 is in place, as shown in Fig. 2, and engaged by the bolts 30, it is retained by' nuts 32 secured upon the bolts 30 below the cap and locked against displacement by lock nuts 33.

Rising from the cap 29 at the center thereof is a bearing sleeve 34 through which extends the stem or central opening 37 in the top wall 38 of the member 16. To facilitate the manipulation of the grate, the stem thereof is provided at a point below the cap 29 with a, .crank 39. This arrangement renders the grate readily accessible for manipulation, while the. generator is in operation, and at the same time enables it to be entirely removed from the generator with the cap 29, to facilitate cleaning and repair.

In the wall of thelower air chamber 28 is provided a vent 40 closed by a cover 41. .The vent 40 is normally closed, but is designed to be opened to permit a natural draft when the engine is not runningpor to facilitate the removal of ashes if such becomes desirable before the full charge of coal has been consumed.

The gas producing or generating chamber 42 is located between the upper and lower members of the generator between which is interposed a cylindrical wall 43 of fire clay or other suitable material. The wall 43 is located just within the series of air tubes 17 and is disposed in closely adjacent relation thereto, so that the heat generated within the chiunber 42, by the combustion of the coal, will heat the air tubes to a high temperature. The waste heat of the generating chamber is thus utilized to heat the moist air immediately prior to its delivery to the lower air chamber 28, from whence it passes to the genenitingchamber 42. In order to minimize the loss of heat by radiation from the tubes 17, the latter are insulated by asbestos or other suitable standard 35 of a grate 36 located within an enlarged purpose of regulating the tension of the spring 24. By

This gas ouilet is protected, to prevoni' the log ihereoi, by the tapered lower end -18 of the hopper l9, it being observed lxban this lower end of the hopper 19 exte ds nearly to the lower side 0'!" the gas outleL and is suliicieu y tapered. to produce surrounding space which v. ibus permitting free escape of the gas by way of LllO ouL- lot- The bellow Lerods or air tubes 17 may be screwed or secu.=.e(l in any other suitable manner to the member-e 1" and i6, our v prefer 11MB, these tubes are tbrougli openings in the walls of the members and. m provided tli 17 which may be screwed up to no ruforming a gas uoei's l1: nod ll} ngai, so the opposite apparel-us is as follows: Assurm tent fuel is located in the iulei. 2i where it serves to coo the Wfll theliopper l9 and. i 'inilially d.
